WebSilicate minerals can be thought of as three-dimensional arrays of oxygen atoms that contain void spaces (i.e., crystallographic sites) where various cations can enter. Besides the tetrahedral (4-fold coordination) sites, 6 … WebAbout 1,000 silicate minerals have been identified, making the silicate minerals the largest mineral group. Silicates are minerals that contain silicon atoms bonded to oxygen atoms. The basic building block for all silicate minerals is called a tetrahedron, where one silicon atom is bonded to 4 oxygen atoms (Figure 3.6).
